Subject: Re: [PSUBS-MAILIST] Interior low
level lighting
I wonder if LED's could be rigged for submergence
on the dash of my wetsub? I like John's idea for insuring seeing his switches
in total darkness.
In the murky water that would be a definate
benifit for me in the wetsub. Being able to see the led light next to my
switches would aid in making sure
I used the correct ones when in extremely low viz
situations. Of course in that viz case, it would be time to terminate the dive
due to low viz, but DURING
the dive before it was terminated for low viz, it
could be a real help. Any ideas?
Bill.

Interesting thread. I think I'll be sure
to bring my forehead mounted trilight: It has red LED's for preserving night
vision. A little off the cuff but this thread got me
thinking.
